Cloud computing is a computing model in which IT services and resources (hardware and software) are sold and delivered over the internet. Try to understand it with the help of an example; the email that you are using (Gmail, Yahoo, Hotmail and Rediffmail) helps you to store all the valuable information on the internet. You no need to worry about the software and hardware required to store these mails. You just need a computer and internet connection to access your email account.
Irrespective of the software’s installed on your computer, you can access your email on your computer. Your email is not configured on your local computer; you just access it through internet connection. All the data that you store on your email is actually stored at a server located at a single or multiple locations. It comes under a type of cloud computing known as SAAS (Software as a Service). The cloud helps you to access your information from anywhere at any time. Google doc is also an example of cloud computing where you can create a word, excel or PowerPoint document just using the internet. You no need to install MS office software on your computer. You can create your documents directly on Google docs.
On the other hand, a general computer setup requires you to be at the same location where your data storage device is placed. With cloud computing, you can access your storage device from anywhere. Your cloud service provider can have their own or rent the hardware and software necessary to run your business applications.
Cloud computing helps those small businesses that cannot afford the same amount of hardware and storage space as a larger organization can have. They even cannot buy the application software’s necessary for their business. These smaller organizations store their information in the cloud and reduce the cost of purchasing the software’s and storage devices. Using this service, the chances of wastage of storage space can be overcome as you can reduce the subscription of your storage capacity as per your business requirements.
The basic requirement is to have an internet connection to access the cloud computing. It means, if you want to access a specific document that you have housed in the cloud, you must first establish an internet connection either through a wireless or wired internet or a mobile broadband connection. The benefit is that you can access the same document from wherever you are with any device that can access the internet. These devices can be a desktop, laptop, tablet, or phone. This can also help your business to function more smoothly because anyone who can connect to the internet and your cloud can work on documents, access software, and store data. Imagine picking up your Smartphone and downloading a pdf document to review instead of getting it printed or upload it to your laptop. This is the freedom that the cloud can provide for you or your organization.
